Stone co-founded Black Rocket in 1996 with partners Bob Kerstetter and John Yost. Four years later, the partners sold a majority stake to Euro RSCG and the shop was eventually shuttered. Stone says he's excited to be at a startup again. "We all wanted to be part of a small thing again and we just kind of looked each other and said, 'Lets just try it,'" he says. "It's funny, because there have been a lot of articles about the demise of San Francisco creativity and about how all the accounts are leaving town and we're sitting here saying, 'Wait a minute.' We're optimistic."
